我运行的是 Ubuntu 16.04.1 LTS
我知道有很多关于这个问题的问题，但是都没有解决我的问题。我学习函授课程，所以我需要能够播放我的 DVD。有些课程似乎可以正常播放，而其他课程可以播放，但只能在某些磁盘上播放（学校的帮助告诉我们使用 VLC，哇，太有帮助了，哈哈）。我可以看到磁盘中的所有文件，没有任何问题（这意味着我可以毫无问题地访问文件？），但我无法播放 vob 文件（奇怪的是其中两个文件可以播放），或者在 vlc 中加载 DVD。我已经安装了 Libdvdread5 和我读到的所有其他软件包，使用区域设置将我的区域设置为 1，并在 vlc 中选择“无光盘菜单”。但无论我做什么，似乎都无法播放。我知道 DVD 没问题，因为它可以在便宜的东芝阅读器和我妈妈的 MacBook 上播放。vlc 日志为：
